and regional NWP models. In the global model there are changes to improve boundary-layer processes, the representation of cloud, radiation, warm rain microphysics, and deep convection, whilst in the regional models there are improvements to the treatment of lying snow, sub-grid turbulence and ice

On Monday, early low cloud and isolated fog patches in southern and western areas will soon lift, giving way to widespread sunshine, particularly across central England. Some shallow cumulus and stratocumulus cloud may develop in the south, but it will remain dry. Further north and west, conditions

December 2018: Satellite image of spiral shaped cloud 07 December 2018 High resolution data from the Moderate-resolution Imaging Spectro-radiometer (MODIS) on board NASA's Aqua satellite shows this low-pressure system centred off the North coast of Scotland on 7th December. The anti-clockwise swirl

and a clear start in the north-west, with more cloud elsewhere, but with western areas turning sunny by afternoon. The 3rd started cold in a few places, with sunshine in the north-west and south-west spreading to all but south-eastern areas by evening. The 4th began frosty in most areas, with early

Thunderstorms are associated with numerous hazards including heavy rainfall and lightning. In addition to these hazards, tiny ice crystals can form within the storm’s rapidly growing clouds. These high-altitude crystals can be particularly dangerous to aircraft as they can stick to aircraft

, the increase in the resolution leads to a loss of compensating errors and thus increases the temperature bias compared to the lower resolution version. We reformulate some of the sub–grid scale physics parameterisations and model chemistry which produces an improved representation of cloud cover
